3D vena contracta area to quantify severity of mitral regurgitation: a practical new tool?
M itral regurgitation (MR) is a common form of valvular disease1 and its severity is associated with excess morbidity and mortality from left ventricular (LV) remodeling, left atrial remodeling, pulmonary pressure elevation, and progression to left and right heart failure.2-6 Current American Society of Echocardiography (ASE) Guidelines7 propose vena contracta (VC) width as a simple semi-quanti...
متن کاملDiagnostic value of vena contracta area in the quantification of mitral regurgitation severity by color Doppler 3D echocardiography.
BACKGROUND Accurate quantification of mitral regurgitation (MR) is important for patient treatment and prognosis. Three-dimensional echocardiography allows for the direct measure of the regurgitant orifice area (ROA) by 3D-guided planimetry of the vena contracta area (VCA). We aimed to (1) establish 3D VCA ranges and cutoff values for MR grading, using the American Society of Echocardiography-r...
متن کامل3D vena contracta area after MitraClip© procedure: precise quantification of residual mitral regurgitation and identification of prognostic information
BACKGROUND Percutaneous mitral valve repair (PMVR) is increasingly performed in patients with severe mitral regurgitation (MR). Post-procedural MR grading is challenging and an unsettled issue. We hypothesised that the direct planimetry of vena contracta area (VCA) by 3D-transoesophageal echocardiography allows quantifying post-procedural MR and implies further prognostic relevance missed by th...
متن کاملAssessment of aortic regurgitation by live three-dimensional transthoracic echocardiographic measurements of vena contracta area: usefulness and validation.
In this report, we evaluate 56 consecutive adult patients who underwent standard two-dimensional (2D) and live three-dimensional transthoracic echocardiography (3D TTE), as well as left heart catheterization with aortography (45 patients) or cardiac surgery (11 patients), for evaluation of aortic insufficiency. Similar to the method we previously described for mitral insufficiency, aortic regur...
متن کاملComparison of vena contracta width by multiplane transesophageal echocardiography with quantitative Doppler assessment of mitral regurgitation.
Mitral regurgitation (MR) severity is routinely assessed by Doppler color flow mapping, which is subject to technical and hemodynamic variables. Vena contracta width may be less influenced by hemodynamic variables and has previously been shown to correlate with angiographic estimates of MR severity. This study was performed to compare mitral vena contracta width by multiplane transesophageal ec...
